STOP-MOTION FOR RAILWAY-HEADS.

SPECIFICATION forming part of Letters Patent No. 327,696, dated October 6, 1885.

Application filed August 23, 1884. Serial No. 141,331.

To all whom it may concern:

Be it known that I, CHESTER E. KING, of Phenix, in the county of Kent and State of Rhode Island, have invented a new and Improved Stop- Motion for Railway-Heads, of which the following is a full, clear. and exact description.

The invention consists in an improved mechanism for stoppinga railway-head or drawingroll when the sliver breaks.

The improvement is embodied in the construction and combination of parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a sectional side view of part of a railway-head having my improved stop mechanism applied. Fig. 2 is a plan view of the same. Fig. 3 isa detail plan view illustrating the beltshifting mechanism.

A indicates the table or frame; B B, the draft-rolls; O, the trumpet, and D D the calender-rolls. The sliver passes from a series of carding'machincs (not shown) between the draft-rolls B B, through the trumpet O, and between calender-rolls D D into the can usually provided to receive it.

E indicates a trip-lever, which is pivoted to the frame or table A and projects laterally, Fig. 3, so as to engage with the belt shifting lever F.

A lever, 12, made preferably of a small iron rod, is pivoted in a standard, a, fixed on table A at the side of trumpet G. 011 the longer arm of said lever is fixed a concave plate, f, that extends close in front of and parallel to (No model.)

the drawing-rolls B B, and rests on the sliver.

The shorter arm of lever f extends forward and downward, and its end is bent laterally to adapt it to bear against one arm of a V-shaped lever or dog, d, that is pivoted in vertical po sition to the inner end of trip-lever E. The other arm of said dog (I has a claw, d, for engaging a lug, e, on the lower roll D. This engagement occurs when a sliver breaks, since the platef then falls, and thus causes the lever to throw the dog (1 forward, as illustrated by dotted lines, Fig. 1. Owing to themomentum of the roll the dog d is raised, and with it the inner end of catohlever E, so that the latter is forced to release the lever F, whose spring 9 then throws it laterally and causes the belt (not shown) to shift from the driving-pulley to the loose pulley,which of course arrests the operation of the machine.

The plate f prevents the broken sliver from winding'on the rolls B and injuring the rollcovering.

What I claim is The combination, with the draftrolls and a belt-shifting spring-actuated lever, of the pivoted lever 12, provided with the plate or arm f, arranged in front of said draft-rolls, the catch-lever E and dog attached thereto, and the calender-rolls, one of which has 2. lug for engaging said dog, substantially as shown and described, for the purpose specified.

CHESTER EARL KING.
